Problems with the city’s 911 system continued through the weekend, with at least one service outage that forced backup systems to kick in so emergency calls could get through, The Post has learned.

Meanwhile, a top City Council member announced plans yesterday to hold hearings on the trouble-plagued 911 system. A host of officials, including three mayoral candidates, also expressed concern that the system is getting worse — not better — even after $2 billion was spent to improve it.

The Post reported yesterday that the Bloomberg administration is trying to suppress a shocking report — commissioned by the mayor himself — that shows the 911 system and dispatch networks are disasters waiting to happen.

“It raises a lot of concern,” Council Public Safety Committee Chairman Peter Vallone Jr. (D-Queens) said of The Post story.

“We’ve learned what happens when there are contracts involving technology that have not had proper transparency,” Vallone added, citing the CityTime payroll scandal.

Bloomberg spokesman Marc LaVorgna insisted the analysis “is still ongoing . . . and the review will be completed shortly and released.”
